Using your travel eSIM as a hotspot for laptops, tablets, partners

Most travel eSIMs allow personal hotspot (tethering) by default. But the policy varies more than you'd expect, and a few popular providers throttle or ban it. Always check the listing before you buy if hotspot matters.

Providers that allow hotspot

• Airalo — yes, all regions.
• Holafly — yes, but the daily fair-use cap (~5 GB) hits tethered traffic faster.
• Ubigi — yes, full speed.
• Saily — yes.

Providers with caveats

• Redteago — varies by partner. Some country bundles ban hotspot; the listing should disclose.
• Local prepaid SIMs sold as eSIMs — often hotspot-blocked by the carrier (T-Mobile prepaid Connect in the US is a famous one).

How to enable

• iPhone: Settings → Personal Hotspot → On. Allow Others to Join.
• Android: Settings → Network → Hotspot & tethering → Wi-Fi hotspot.

Most phones let you pin the hotspot to a specific SIM. Make sure it's pointing at the travel line, not your home one.

Watch for these

• Throughput — hotspot performance is gated by the host phone's antennae and the local cell, not the eSIM. Expect 20–60 Mbps in cities; less in rural areas.
• Battery — running hotspot all day will drain even a Pro Max in 4–6 hours. Pack a power bank.
• Heat — long hotspot sessions cook the phone. Both Android and iOS throttle once they're hot, so download big files early.

When you should buy a separate device

If you'll burn more than 30 GB on tethering or you want the laptop always-on without leashing your phone, get a pocket MiFi or a programmable cellular dongle. A 9eSIM card can also go into many travel routers (TP-Link M7350, GL-iNet Mudi) — same profile management, different host.
